Energy Quiz
Q1: ________ is the process of heat
moving through direct contact of two
objects.
A: Conduction
Q 2: Which object has MORE
Gravitational Potential Energy at
it’s current position?
A: The Apple (It’s
higher up)
Q 3: A windmill generates electric
energy by using ______ energy from
the moving of it’s blades.
A: Mechanical
Q 4: The amplitude of a wave will
effect a sound by changing the
__________ you hear.
A: Volume (“loudness”)
Q 5: When you think of electric
energy, it is acceptable to always
think of it as:
A: Electricity
Q 6: The color you see is controlled
by what property of a wave?
A: Wavelength
Q 7: Refrigerators often use
_________ to move cool air
around to cool the food.
A: Convection
(cool air sinks)
Q 8: Which form of energy is often
made during an energy transfer but
is “lost” into the air/space?
A: Heat
Q 9: What is wrong with the energy
flow chart that represents how a
human gets their energy?
Nuclear
Light
Chemical
Electric
Mechanical
A: Electric. (Humans
don’t “plug in” for electricity)
Q 10: Two marbles sit on a
ramp. Which will move the cup
more at the bottom?
A: The one with more mass
(not necessarily the “larger” one)
Q 11: Where would I place the smaller
mass marble to accomplish the same
amount of energy the larger mass
marble will do on the cup?
=?
A: Higher on the ramp!
(More height = more GPE!)
Q 12: In order to use the
mechanical energy in a blender,
which form of energy would be
helpful to get first?
A: Electric
(plugging it in)
